Good. I'm glad to see some "bites " on this one.

If Diadectomorpha is the sister group to Amniota, which genus in both are 
sister taxa (or closest to the node)?

Why are Solenodonsaurus and Procolophon not considered close to this group (see 
below)?

from D. Marjanovic: 

Diadectomorpha
|--*Limnoscelis*
`--+--*Tseajaia*
   `--Diadectidae
        |--*Ambedus* (or: How Not to Form a Latin Noun From a Verb)
        `--+--*Orobates*
           `--+--*Desmatodon*
              |--*Diasparactus*
              `--*Diadectes*

If Westlothiana is the basalmost lepospondyl, which genera are its closest 
sister taxa? 

Why not Paleothyris?


If Macrocnemus is an archosaurosaurormorph, which taxon is its closest sister 
taxon?

Why not Jesairosaurus?
